The eyes and notochord (like a spine) go next. Finally, the brain is absorbed. Having no need to move about anymore, all of these body parts are considered superfluous by nature and dispensed with (an intriguing indicator that eyes and brains are necessarily mainly for reasons of mobility and are unnecessary for stationary organisms like plants—no wonder many of us feel an urge to travel). The material is then recycled to create whole new body systems, including digestive, reproductive, and circulatory systems. Then the hermaphroditic tunicate reproduces, expelling brand new sea squirts into the world. It doesn’t get much more alien than that.

If you believe in ghosts and paranormal activities, then you are gonna watch the most of all of them in here. Several mysterious incidents happen around the world that is totally unexplainable to the world of science and people still haven’t figured out what these really are. We have captured a lot of such nerve breaking real videos and you can go through stories of haunted houses, paranormal activities and unfathomable presence of figures and objects in the real world we all live in. Tune in and dive deep into those elements you might have never seen or heard.

Want to give an arachnophobic diver a heart attack? Put a Japanese spider crab in his path. These critters have very, very long legs which can extend up to 12 feet. Despite their somewhat intimidating appearance, they are reported to be quite docile and friendly, and a lot less scary than many of the more innocuous looking species that inhabit the ocean floor. “These small geckos are native to Madagascar. Other leaf-tailed geckos of the genus Uroplatus share a similar flattened tail, but the satanic leaf-tailed gecko has arguably the most leaf-like tail when compared to congeners. This is a fairly old photo, but proves that you can take nice photos with relatively cheap cameras. This was only a 3.2 megapixel Nikon Coolpix 3700…well before I had begun shooting with a DSLR.” – Mike Martin This video, uploaded by British water company United Utilities in April 2011, showed three clips of a maintenance robot running across some sort of creature in the sewers under the St. James neighborhood of London. The internet population quickly began wondering if this was some sort of genetic experiment or just an escaped monkey before someone put together that it was April and United Utilities had a “What Not To Flush” campaign running to educate people about proper sewer usage. Yeah, a water company pulled a viral April Fools' Joke that’s still circulated as legitimate. It only lives on because of how creepy it it. Chrysomallon squamiferum is found around inhospitable Indian Ocean hydrothermal vents, extreme ecosystems in 8,000 feet of water. Water temps can reach over 700°F, and biological communities sprout up where the salt water and extreme heat interact. Here, armored snails use iron sulfide to build their shells — the only animals on Earth to use iron in this way. Black metallic scales also cover the foot.
Make no mistake — those tree trunks seen above are not saplings. That's right, those crabs are huge! Growing up to a meter in length from leg to leg, these terrestrial hermit crabs are the largest land-living arthropods in the world. Although they are omnivores that have been known to consume turtle hatchlings, they generally prefer to eat fleshy fruits and, you guessed it, coconuts! Eunice aphroditois is ingeniously named after the infamous Bobbitt family incident of the early ’90s in which Lorena Bobbitt cut off her husband’s manhood with a kitchen knife. The hunting method of this giant polychaete worm is said to resemble Lorena’s modus operandi. The worm emerges from the silty ocean floor at dusk and waits motionless with its iridescent body standing at attention 6 inches out of the substrate.
Gather round, children, and let me tell you about a time before the internet, when our phones were attached to the walls and we bought music stored on physical objects that we played in our cars. Back then, secret groups of videophiles collected creepy, avant-garde, and extremely weird clips stored on tapes. We even believed that a Japanese ghost could haunt a VHS cassette.

The Angora rabbit is an animal that seems to have an eternally bad hair day. One of oldest types of rabbit in the world, it’s bred for its long, soft, silky hair. This is a very high maintenance animal since it needs to be sheared every few months. Apparently, their long fur can cause these rabbits to sometimes overheat. And we all know there’s nothing worse than having a rabbit melt on your carpet.

It’s been nearly a decade since it was first uploaded, but “I Feel Fantastic” is still only a little less mysterious than when it first captured the attention of the internet. The featured robot, Tara the Android, is the creation of an robot hobbyist who calls himself "John Bergeron." The plan was for Tara to be the first android pop star, but the bizarre description on the YouTube upload that references Pygmalion and a cutaway from I Feel Fantastic to an outdoor location gave birth to several online urban legends. Is Tara a harmless pop star, or a robot built in the image of a murder victim? A headless goddamned ghost appears right in goddamned front of them. You literally see it materialize on camera -- of all the entries on this list, this is the one you absolutely have to watch (here's a shorter version that cuts right to the ghost if you don't have 4 free minutes). Seriously, your mind will be blown like Eric Stoltz's penis in The Rules of Attraction. As they swing the camera lazily through the room, the ghost just walks very purposefully toward them like it's delivering a pizza, while a long, low moan emanates from its phantom lungs. Known for its luscious red lips!, the red lipped batfish is native to the waters of Galapagos Islands. Ironically, it’s a bad swimmer and uses its highly-adapted pectoral fins to walk on the ocean floor. Some scientist believe the purpose of its red bright lip is for the male to attract the female. Yes its the male with the red lips! This fish lives in tropical climates and on the depth range of 3 to 76 meters below sea level and poses no threat as such.

Just as the Cleveland Museum of Art was preparing for the special Monet exhibit Painting The Modern Garden: From Monet to Matisse, the museum's director of architecture and design snapped this spooky photo of a mysterious figure looking down on the gallery. The "ghost" had an uncanny resemblance to the French Impressionist painter himself, and Kelly Notaro, communications associate for the museum told TODAY that "this snapshot taken by a staff member is not retouched or photoshopped, and we've heard from others that they've seen the man." Talk about a unique way to launch an exhibit.

The saiga antelope is known for its large distinctive nose, which can flex and inflate to help it breath better in dusty summers and harsh winters of the Kazakhstan. In the summer, its coat is thin and tawny, but in the winter it grows a wooly pelt. The saiga antelope is a major player in one of the most spectacular animal migrations. It faces an uncertain future due to hunting and loss of habitat.
The Angel of Catalonia video has accumulated millions of views since its upload in 2006 and has made several lists on the internet “proving” ghosts and the paranormal are real. In the video, two men hit record on their camera as they enter a forest outside the town of Campdevànol, Spain, then come across some large feathers in the woods. Finally they pan over to what looks like a man with open wounds on his back, who turns and looks at them, catching a reflection in his eyes. The video is a very well produced hoax by some Spanish horror film fans who used to explain their process at a now-defunct making of site (but the Wayback Machine never forgets).

​Galeopterus variegatus, also named Sunda Colugo or the Sunda Flying Lemur, is a nocturnal and arboreal (lives in trees) mammal endemic to Indochina and Sundaland. These animals possess large membranes of skin called patagiums that extend along the limbs, allowing them to glide along distances of up to around 100 meters; given that these animals are only around 40 centimeters in length that's pretty impressive skills! The mottled coloring of these animals also makes them look a bit like the lichen of a tree and therefore helps to camouflage them.

When Ian Wrin and April Russ stopped by Tujague's, New Orleans' second oldest restaurant, they were shocked to discover that a ghost had been hovering behind them in one of their selfies. Poppy Tooke, radio host of Louisiana Eats, explained that the "ghost" was Julian, a famous actor of the silent film-era, who once starred alongside Rudolph Valentino in Aisle of Love. In addition to being quite the thespian, Julian, a cross-dresser whose alter ego was Vesta Tilley, had his own makeup line and his picture had been hanging on the restaurant's wall since 1917...until two years ago, when it was relegated to the attic. Not so pleased with the move, Julian has apparently been haunting the restaurant ever since. The two men are apparently investigating strange noises. It's not totally unbelievable that they would want to bring a camera along -- strange noises potentially mean a large and equally strange creature, so it would behoove them to get it on tape. As they follow the noises, they start to find giant white feathers, which honestly are kind of out of place in the middle of the forest, seeing as oversized swans and/or geese typically don't go tearing through the underbrush at midnight:
Not content with only one platform, we’re committed to montages from Vine, Twitter, Instagram, Facebook, Snapchat, and Musically. Sit back and enjoy a veritable fail army: kids fails, animal fails, girl fails, trampoline fails, car fails, on the job fails, old people fails, school fails, water fails, prank fails and pranks gone wrong, funy fails and more!

It’s a maze game that has bizarre flashes of black and white photography as well as disturbing audio samples, like a monologue that Charles Manson gave from San Quentin to NBC in the 1980s and images of child sex offender Jimmy Savile and Margaret Thatcher promoting the National Society for the Prevention of Cruelty to Children. No one knows the purpose of the game and one of the creepy in-game children will eventually begin following you, causing “contact damage” and ending the game.

It’s been found in every ocean except the Arctic, at depths ranging from 2,500 to 7,000 feet. The jelly’s dark-red color affords it a high level of camouflage at depth, as red light doesn’t penetrate deep water. Stygiomedusa gigantea has also been found with the rare fish Thalassobathia pelagica swimming around and living within its medusa. It is believed that the fishes share a symbiotic relationship. Approximately 99 percent of "supernatural" videos can be revealed as hoaxes simply by asking "Why was anyone filming this?" As much as Cloverfield and The Blair Witch Project have attempted to convince us otherwise, people usually don't have cameras glued to their faces unless they know someone is about to be shot out of a cannon or something. So that's our question as soon as this video opens:

A year passed and they returned to the lagoon as a memorial, but as they approached they saw their friend standing there, head bowed. Excitedly they called to him and began running towards him, but he didn’t turn. As they got closer they called him more desperately, but still to no avail. With joy they ran towards him, but stopped dead when they saw not one but five crosses on the waterside.

All madness aside, what really made the Stanley Hotel famous was when author Stephen King actually lived at the hotel for a time and had his own ghostly experience. King reported seeing a faint ghostly figure at the top of the stairs one night before bed. It was this mysterious sighting he witnessed, that inspired King’s movie The Shining. The hotel now runs the film version of “The Shining” on a continuous loop to the guest televisions.

“The Trump administration can take the wind out of the sails of anti-fossil arguments, and give judges far less reason to block projects like Keystone XL in the future if it rescinds the EPA’s GHG “Endangerment Finding.”FACT CHECK:The Trump administration recently released the National Climate Assessment which outlines the dire consequences of anthropogenic global warming in detail.
If an anteater and an armadillo had a baby, it might look something like the pangolin, an odd-looking mammal found throughout parts of Asia and Africa. The pangolin has a long, specially adapted tongue for eating ants and termites and wears a protective keratin shell — it is the only mammal known to have this adaptation. Sadly, its unique characteristics also make it the most trafficked mammal in the world, as it is highly sought-after for its meat and armor. The pangolin is currently listed as a threatened species.

“I was very surprised to find these giant hare-like animals just wandering freely around the children’s play area in Nottingham! They are called Mara or Patagonian Hares, and they are quite big with very spindly legs. They seemed very calm and just nibbled on grass. I guess they can’t be too dangerous! I saw a family of these hares watching steadily at the visitors.” – Ranjit Pol

The goblin shark is, without a doubt, one of the weird ocean animals that looks more like the predators from the thriller shark movies. This living fossil sports a protruding nose or stout to detect its prey. Along with its unique and extendable jaw that appears to unhinge when feeding, the overall appearance of the goblin shark is both fascinating and terrifying at the same time. Also known as the Thorny Devil, this lizard has a body covered with thousands of spikes. These spikes are thought to make predators think twice before attempting to swallow a thorny devil. Not only does their spiny armor protect them from predators, it also helps them absorb water in their arid habitat. There are hygroscopic (moisure-attracting) grooves between their thorns. They obtain water from the dew that condenses on their bodies overnight, during rare rainfalls, or by brushing up against dew-coated grass. Any water that gets into the grooves between its thorns is drawn by capillary action to its mouth, allowing the thorny dragon to suck water from all over its body. It’s the most wonderful time of the year: Halloween! And the only thing more fun than celebrating with a "sexy [insert inanimate object here]" costume and downing candy corn shots is not doing that and instead downing something pumpkin-flavored under a pile of blankets while watching some truly terrifying content. If you’re stuck for ideas, here are 13 of our favorite (read: scariest) classic ghost movies guaranteed to keep you up all night thinking, What was that? Did you hear that?! TURN THE LIGHTS ON.

When they hatch, they quickly infect other local anemonefishes. Parasites, by definition, don’t aspire to kill their host. After all, if the host dies, the parasite loses its home and food source. However, in the case of the tongue-eating louse, some individuals can grow to be so large that the hapless anemonefish struggles to close its mouth. Eventually, as you might imagine, this hinders the host’s ability to eat. ​Galeopterus variegatus, also named Sunda Colugo or the Sunda Flying Lemur, is a nocturnal and arboreal (lives in trees) mammal endemic to Indochina and Sundaland.

"Rubber Johnny" is not just British slang for a condom. It’s also a very disturbing art film by Chris Cunningham for the band Aphex Twin. The video originally hit the internet in June 2005, and what was supposed to be a 30-second commercial for Aphex Twin music became a short film about a deformed raver who lived in a basement with his chihuahua. Practical make-up effects were combined with quick editing and video shot in night-vision mode to make the whole thing seem trippy, weird, and disturbingly tactile.

Speaking of ghosts and tourist attractions, another haunted "spirit" of a woman was spotted in an Acadian Village cabin in Louisiana earlier this year. We're not really sure what the back story is on this one, but we do know that the attraction is dedicated to Cajun history in the 1800s. So, based on that, we're guessing the "ghost" might've been a basket weaver or corn shucker back in the day.
